β˜•πŸ§¬ When #coffee beans are cooked, heat changes their #chemistry and creates new bitter molecules.

We humans have a specific gene that acts like a sensor on the tongue to detect these flavors. Some people have sensors that are very sensitive to bitterness while others don't, which explains why a drink might taste different to every person.

Initial thoughts on using ZnCl2 instead of NaOH:

- I like that cleanup is much easier - no need to neutralize before disposing.
- It seems to take longer to plate. Maybe because the zinc ions aren't reduced as easily?
- I'm using 1M ZnCl2, perhaps I need to increase that concentration to help provide the ions for plating.

#chemistry #teaching


Today in the classroom:

First year chem are making a brass alloy using pennies and zinc. We'll chemoplate the penny with powdered zinc in ZnCl2. Then, we heat the zinc coated penny to create a shiny "gold" penny. This is a good lab to show students that mixtures can be solids.

Second year will explore how pH changes with H+ ion concentration. They'll dilute some samples, collect pH, then compare their molarity with the calculated pH value.

TIL about M87 the Super Massive Black Hole in the Messier87 Galaxy

One internet article states its distance at 55x10⁢ light-years away. It spins at 860 x 10⁢ km/h!

Quotes from Wikipedia differ a bit

The black hole's mass = (6.5 Β± 0.2stat Β± 0.7sys) Γ— 109 Mβ˜‰.

[76]This is one of the highest known masses for such an object. A rotating disk of ionized gas surrounds the black hole, and is roughly perpendicular to the relativistic jet. The disk rotates at velocities of up to roughly 1,000 km/s (2,200,000 mph) or 1⁄300 the speed of light,[77]
